t IMPROVEMENT IN mwa-RAME The Schedule referred to n these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that I, JOB G. LUsCoMB, of Taunton,

in the county of Bristol, and State of Massachusetts, haveV invented a new anduseful Improvement in FlyvFrames for roving-machines; and I do hereby 'declare that the following is a full, clear, and exact description'thereof, which will enable others skilled in the art to mak`e and use the same, reference being had to the accompanying drawings, forming part ot' this specification, in whichj Figure 1, Sheet I, represents a front elevation of my improved fly-frame.

Figure 2, Sheet II, is a vertical transverse section of the same, taken on the plane of the line x x, fig. 1.

Figure 3,V Sheet II, isa detail horizontal section, on

Y an enlarged scale, of the same, taken on the plane of the line y y, fig. 2.

Figure 4, Sheet II, is a detail vertical section of the same, takenon the plane of the line z z, fig. 3.

Similar letters of reference indicate corresponding parts.

This invention has for its object the production of a new apparatus for adjusting the belt on the cones ofally-frame, for regulating the velocity of the bobbins.

The invention consists in a novel arrangement of devices for connecting the rack, by which the belt is adjusted, with the contact-shaft, and with a clutchgear, whereby certainty of action, and a suitable degree of decrease of motion are obtained.

All the racks heretofore used on ily-frames were connected with very complicated apparatus, and their operation was ineffective.

The action of my apparatusP is positive. used with cones of suitable length, and its degree of motion can be changed with very ,great facility.

A, in the drawing, represents the frame-work of my improved apparatus.

B is the sliding pack, supported in a horizontal positon on the frame A, and connected in suitable manner with the belt G of the cones D E, as indicated in 1.

F is the contact-shaft, which is, by a segmental pinion, a, geared with -the upper cone, D, and its action is controlled by means of a spring, and by two arms, b b, as usual. It thereby receives intermittent rotary mot-ion, and transfers the same, by suitable gearing, c, to `a horizontal shaft, G, which has .its bearings in arms attached to the frame A, as is clearly shown in f1 1.

glhe shaft G is, by means of a bevel-pinion, d, con nected with a bevel-wheel, c, which is fitted upon a vertical arbor, f, that projects from an arm, y, of the frame A.- j

On the arbor f is also mounted a pinion, 71, which meshes into a toothed Wheel, t, that revolves loosely on a pin, j, that projectsfrom the arm y.

The pin jis fitted through a curved slot in the arm g, which slot is part of a circle described around the arbor f, and the pin 7' can therefore be adjusted in the slot, and still be always equidistant from f.

On the pin j /is tted another toothed wheel, k, which is, by means of a pin, l, or by otherj suitable means, connected with the wheel t', so as to tum with it.

The wheel k meshes into a toothed wheel, m, that turns loosely on the rack-shaft I-I. Thus the motion of the contact-shaft is transmitted to the lsaid wheel m on the rack-shaft.

The 'velocity of the wheel m is regulated by adjusting the piu j in the slot, so as to allow a larger or smaller wheel to be used for the wheel la. Thereby the motion ofthe rack can be varied at pleasure, without varying that of the contact-shaft. p

On the rack-shaft H is arranged a sliding clutch, I, which, when let down upon the wheel m, as in lig. l,

will connect the same with the shaft H, so that the latter will also be turned.

On the shaft H is mounted a toothed wheel, n, which meshes into the rack B, so that thus the motion of the contact-shaft is transmitted to the rack.

, The clutch I is, by means of' a fork, o, connected with a bell-crank, J, that is pivoted to the frame A, as shown in fig. 1. i

This bell-crank is, by means of an arm, K, con*-l neeted with la lever, L, thatis pivoted to the upper part of the frame A. j

An arm projects from the lever L, to carry aweight,

M, that has the tendency to swing the lever so as to raise the clutch oill the wheel m.

N is a notched bar, pivoted to the end ofthe lever L, and secured in position by means of a notch or' shoulder thereon, catching overa fixed plate, p, as indicated by dotted lines in fig. 1.

In fig. 1 the parts are represented as ready to work. The belt C is on the thin end of the convex pulley, the clutch is in gear, and the rack as far out as possible.

As the operation proceeds, the rack will be gradually moved in the direction of the arrow shown infg.

'1, and will thereby gradually move the belt C toward the thicker end of the cone E, to make the bobbins turn slower.

A pin, fr, projects from the rack, and works under the bar N, as in fig. l.

4When the belt O is on the thick end ofthe cone E, the piu fr strikes a rounded shoulder formed on the bar N, and raises the said bar od the plate 1). Thereby the weight M is free to act on the lever L, which is swung so as to push the rod K, and to swing the crank J, and consequently raise the clutch olf the toothed wheel m. The rack is thus instantly thrown outof gear as soon as the bobloins` are full.

The lever L may have au upper arm, s, which is connected with the shipper-bar O, so that when the bar N is thrown ol the plate p, the main belt may also be thrown upon the loose pulley.

When the rack-bar is thus out of gear, the rack shaft H will also be free, and can be turned by hand, to draw the rack back again into its original position, and for this purpose, af erank or hand-wheel, t, is mounted on the shaft H. When the machine is to be restarted, to fill a new set of bobbins, the bar N must be pushed in and locked to the plate p, iu order to have the eluteh thrown into gear.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent-y 1. The combination of the horizontal shaft G and I, as set forth. J OB G. LUSGOMB.
